I got the car running great this weekend by just spending time on it. My problem now is that the IAC seems to do nothing. The IAC position value fluctuates, given whatever I'm doing, but it doesn't seem to actually change the AFR/idle.

What I realized and am going to try today:

In desperation to get the car functioning again I turned the idle screw to get more air. Everything that followed resulted in a smooth idle and some good test drives but AC kills the engine at idle and IAC isn't working. Today I plan to close the throttle plates as much as I can without binding. Then try to tune from there and hopefully the IAC will work.

Aside from that, I could really use some tables to reference but haven't found a whole lot on here.
